Abstract (en)
[origin: WO2009043965A1] The invention discloses a protection of an elevator and a method for protecting an elevator, in which the elevator comprises a machinery brake (7), a safety brake (8) of the elevator car (10), and an electrical drive (1) comprising an elevator motor (3) and a power supply appliance (2) of the elevator motor (3). The protection of the elevator comprises restriction of the output of the electrical drive (1) on the basis of the determined limit value (27, 28) for the stator voltage and/or the stator current of the elevator motor (3) and restriction of the movement (12, 29) of the elevator car (10) on the basis of at least one determined limit value (13, 14, 30, 31, 32) for permitted movement of the elevator car (10). At least one limit value for permitted movement of the elevator car (10) is determined at least partly on the basis of the limit value (27, 28) for the stator voltage and/or the stator current of the elevator motor (3) and the elevator car (10) is fitted to move with a restricted movement during the restriction of the movement of the elevator car (10).
